Hi,
ich habe some hosts running rather old Qemu Versions which sometimes show the
following behaviour:
1) Live Migration
2) One Network Interface (virtio-net) stops forwarding traffic.
3) If I reboot the server I hit the following assertion
qemu-2.9.0: hw/pci/pci.c:311: pcibus_reset: Assertion `bus->irq_count[i] == 0'
failed.
Does anybody remember this kind of error? Is this something that has already
been fixed?
The patch:
commit 3936161f1fd72d1dfa577aaba910819c5e873260

pci: deassert intx when pci device unrealize
If a pci device is not reset by VM (by writing into config space)
and unplugged by VM, after that when VM reboots, qemu may assert:
pcibus_reset: Assertion `bus->irq_count[i] == 0' failed
Is applied to our 2.9.0 tree.
Thanks,
Peter
